Using G_OPTION_ARG_CALLBACK

[Randima Niroshini <randima@xxxxxxxxxxxxxxxxxxx>]

Hi all,

I used "G_OPTION_ARG_CALLBACK" to denote one commandline argument, but it gives
the following error.

./parser.cc:95: error: invalid conversion from 'gboolean (*)(const char*, const
char*, void*, GError**)' to 'void*'

Am I missing out something here?

static gboolean
gparse_cb (const char *key, const char *value, gpointer user_data, GError **error)
{
  

  return TRUE;
}

static GOptionEntry options[] = {
  { "verbose", 0, 0, G_OPTION_ARG_NONE, &gbverbose, "Add verbose output to
standard log", NULL },
  { "version", 0, 0, G_OPTION_ARG_NONE, &gbversion, "Print version information
on standard output", NULL },
  { "parse", 0, 0, G_OPTION_ARG_CALLBACK, gparse_cb, "Parse the program, print
errors on standard error", NULL },   
  {NULL}
};

Thanks,

Randima
